NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Aug 4, 8:15 AM EST, 6 hours 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 915 AM EDT WED AUG 4 2010 .SYNOPSIS... AT 9 AM EDT...SKIES WERE MOSTLY SUNNY ACROSS THE REGION. RADAR INDICATED WIDELY SCATTERED SHOWERS OVER THE MARINE AREA...MAINLY THE OFFSHORE PANHANDLE WATERS. TEMPS/DEW POINTS RANGED FROM AROUND 80/ MID 70S NORTH TO MID 80S/UPPER 70S COAST. WINDS WERE GENERALLY CALM TO LIGHT ONSHORE. AT UPPER LEVELS... THE LARGE SCALE PATTERN REMAINS RELATIVELY STATIC. THIS IS HIGHLIGHTED IN THE NRN STREAM BY TROUGHING OVER THE PAC NW STATES... ONE NOTABLE SHORT WAVE TROUGH ACROSS THE N CENTRAL PLAINS...ANS A LARGE UPPER LOW/TROUGH WILL BE CENTERED OVER HUDSON BAY. IN BETWEEN THESE SYSTEMS...WLY ZONAL FLOW PERSISTS. THE SRN STREAM HIGHLIGHTED BY PERSISTENT AND SPRAWLING RIDGE KEEPING THE WESTERLIES WELL N OF THE REGION. A 597-DM H5 HIGH IS CENTERED OVER ARKANSAS WITH RIDGE AXIS EXTENDING ESE ACROSS NE GULF. CLOCKWISE FLOW AROUND NOSE OF HIGH PROVIDING NE FLOW AND SUBSIDENCE ACROSS CWA. THIS PATTERN WILL BE RESPONSIBLE FOR ANOTHER SCORCHER OF A DAY ACROSS THE DEEP S. DURING THE NEXT 12-24 HRS...THE CANADIAN SHORT WAVE WILL WORK ITS WAY SEWD ACROSS THE GREAT LAKES TONIGHT AND ON INTO NEW ENGLAND. ON THURS PAC TROUGH AMPLIFIES ACROSS THE GREAT LAKES...OH VALLEY AND NERN STATES WITH CORRESPONDING BUILDING OF UPSTREAM RIDGE OVER THE CNTRL AND NRN ROCKIES AREA. WHILE THE BASE OF THIS TROUGH WILL NOT PENETRATE MUCH FARTHER S THAN THE MID ATLANTIC STATES...IT WILL HELP TO WEAKEN THE SRN U.S. RIDGE AND PUSH THE HIGHEST HEIGHTS FURTHER W INTO TX AND NM BY FRI. THIS WILL ALLOW THE SUBSIDENCE INVERSION TO WEAKEN AND FURTHER DIMINISH FLOW IN THE MID AND UPPER LEVELS. THIS WILL LEAD TO MORE UNIFORM DISTRIBUTION OF TSTMS DURING THE AFTERNOONS AND EVENINGS WITH CONVECTION WILL BE ALMOST ENTIRELY FORCED BY SEABREEZES AND BOUNDARY INTERACTIONS. WITH VERY LIGHT STEERING FLOW...LOCALLY HEAVY RAINFALL WILL BE POSSIBLE. AT LOWER LEVELS... A SUBTROPICAL RIDGE WAS NOSING WWD EXTENDING WWD FROM BERMUDA TO VCNTY OF THE LOCAL AREA. THE GRADIENT...HOWEVER...IS VERY WEAK. A COLD FRONT WAS LOCATED FROM NRN MO NEWD INTO THE MIDWEST STATES. THE RIDGE WILL DRIFT TO S OF THE AREA FOR THE REMAINDER OF THE SHORT TERM PERIOD. THE 1000-700 MB FLOW WILL REMAIN WET AND FAIRLY LIGHT. 12Z TAE RAOB WITH 2.2 INCH PWAT...-6 LI AND 3800 CAPE. ON THURS...ABOVE AMPLIFYING TROUGH NUDGES SRN RIDGE FURTHER SOUTH. THIS IN TURN WILL FORCE A COLD FRONT SEWD FROM NRN TX THROUGH THE OH VALLEY AND NERN STATES AND SHUNT SURFACE RIDGE BACK INTO NRN PENINSULA. ON FRI...THE FRONT WILL BE SAGGING SWD ACROSS NRN AL AND GA. THE PRESENCE OF THIS BOUNDARY WILL COMBINE WITH SEA BREEZE TSTMS INDUCED BY ONSHORE STEERING FLOW WILL PRODUCE A FAIRLY EQUITABLE DISTRIBUTION OF CONVECTION. WITH THE RIDGE S OF THE AREA...LOW TO MID LEVEL ELY FLOW TODAY WILL VEER TO THE S BEGINNING ON THURS. DESPITE A RETREAT OF UPPER AND SURFACE RIDGE...A SHIFT FROM THE CURRENT HOT AND OPPRESSIVE DAYS WILL BE ONLY GRADUAL. LOCALLY... TEMPERATURES WILL REMAIN ABOVE NORMAL WITH UPPER 90S ACROSS THE NRN TIER OF ZONES WHERE CONVECTIVE COVERAGE WILL BE LESS...TO THE MID 90S ACROSS INLAND N FL AND LOWER 90S AT THE COAST. HUMIDITY WILL REMAIN OPPRESSIVE WITH DEW POINTS STUCK MAINLY IN THE MID 70S INLAND AND UPPER 70S AT THE COAST. THIS WILL KEEP MIN TEMPS IN THE MID TO UPPER 70S AND DAYTIME HEAT INDICES OVER 105. THIS REFLECTED IN MODEL SOUNDINGS. I.E. GFS TAE WITH PWATS REMAINING ABOVE 2 INCHES THRU AT LEAST SATURDAY. && .SHORT TERM...THIS AFTERNOON INTO TONIGHT. THIS AFTERNOON...YET ANOTHER HEAT ADVISORY REMAINS IN EFFECT...FOR THE WRN 2/3RD OF FORECAST AREA WITH HEAT INDICES PEAKING AROUND 110 DEGREES. HEAT INDICES WILL BE A FEW DEGREES LOWER ACROSS S CENTRAL GA AND THE ERN AND COASTAL PORTIONS OF THE FL BIG BEND...SO THE ADVISORY WILL NOT INCLUDE THOSE AREAS. HIGHS FROM THE MID 90S EAST TO UPPER 90S WEST ZONES. HOWEVER AND STORMS CAN PROVIDED RAPID BUT TEMPORARY RELIEF FORM THESE HOT AND SULTRY CONDITIONS. POPS WERE BASED ON A COMBINATION OF SEA BREEZE CLIMATOLOGY FOR A TYPE 2 REGIME (1000-700 MB MEAN VECTOR WINDS E AT 5-10 KT) WHICH FAVORS WE ALA/FL PANHANDLE AND THE 04/06Z WRF RUN WHICH SHOWED A DECIDED PREFERENCE FOR CONVECTION ACROSS THE FL COUNTIES AND THEN TOWARDS SUNSET...GA COUNTIES WITH EAST COAST SEA BREEZE. SURFACE DELTA THETA-E VALUES WILL BE AROUND 30 ONCE AGAIN ACROSS THE WRN ZONES WHICH WILL SUPPORT WET MICROBURSTS. WILL GO WITH 30-50 PCT POPS...MAINLY NE-SW POP GRADIENT. LOCAL CONFIDENCE TOOL SHOWS AROUND 20 PCT CHANCE OF SEVERE WX WRN HALF OF CWA. WE INCLUDED MENTION OF ISOLATED T+ IN THIS AREA. ALSO...DUE TO THE WEAK ENVIRONMENTAL FLOW...LOCALLY HEAVY RAINFALL WILL BE POSSIBLE. TONIGHT...20-30 PCT CHANCE OF EVE CONVECTION WITH S/CNTRL GA/ SE BIG BEND BEST SHOT. MIN TEMPS IN THE MID TO UPPER 70S. && .MARINE... SEAS ARE FLAT WITH LIGHT OFFSHORE WINDS. WITH THE PRESSURE GRADIENT REMAINING VERY WEAK...SEAS WILL GENERALLY CONTINUE AT 1 FOOT OR LESS WITH A FEW 2 FOOTERS POSSIBLE BY FRI AFTERNOON IN THE SEA BREEZE. WINDS WILL BE 10 KT OR LESS AND BECOME ONSHORE BY THIS AFTERNOON...WHERE THEY WILL STAY FOR THE NEXT SEVERAL DAYS. && .AVIATION...WITH PLENTY OF LOW LEVEL MOISTURE AND STRONG DAYTIME HEATING...SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND BECOME ENHANCED BY THE SEABREEZE. CONVECTION SHOULD BE MORE NUMEROUS ACROSS THE EASTERN FLORIDA PANHANDLE AND SOUTHEAST ALABAMA. WINDS WILL BE LIGHT FROM THE SOUTHEAST TO SOUTH. THERE WILL BE THE POTENTIAL FOR LOCALLY STRONG WIND GUSTS IN THE VICINITY OF ANY THUNDERSTORMS. && .FIRE WEATHER...TEMPERATURES WILL TREND SLIGHTLY DOWNWARD BUT REMAIN HIGH. HOWEVER...AMPLE LOW LEVEL MOISTURE AND SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS WILL ENSURE THAT RELATIVE HUMIDITIES WILL REMAIN WELL ABOVE CRITICAL LEVELS...AND NO FIRE WEATHER CONCERNS ARE EXPECTED THROUGH AT LEAST THE FIRST OF NEXT WEEK. && .TAE WATCHES/WARNINGS/ADVISORIES... AL...HEAT ADVISORY 17-22Z ALL ZONES. GA...HEAT ADVISORY 17-22Z GAZ120>128-142>145-155>157. FL...HEAT ADVISORY 17-22Z FLZ007>014-016-017-026-108-112-114. GM...NONE. && BLOCK/T BARRY

SOUTHWEST AND SOUTH CENTRAL GEORGIA...THE FLORIDA BIG BEND AND PANHANDLE...AND THE ADJACENT GULF COASTAL WATERS. .DAY ONE...TODAY AND TONIGHT... AT THE RISK OF SOUNDING LIKE A BROKEN RECORD...ANOTHER HOT AND HUMID DAY IS ON TAP ACROSS THE REGION. HEAT INDICES WILL PEAK NEAR 110 DEGREES THIS AFTERNOON WEST OF A LINE FROM TIFTON TO TALLAHASSEE TO PORT SAINT JOE. WHILE SOUTH CENTRAL GEORGIA AND COASTAL AND EASTERN PORTIONS OF THE FLORIDA BIG BEND ARE NOT IN THE ADVISORY...HEAT INDICES ARE STILL EXPECTED TO BE HIGH THERE... GENERALLY BETWEEN 103 AND 108 DEGREES. ISOLATED STRONG TO SEVERE STORMS WILL BE POSSIBLE THIS AFTERNOON. THE BEST CHANCE FOR SEVERE STORMS WILL BE OVER SOUTHEAST ALABAMA AND THE FLORIDA PANHANDLE WHERE WET MICROBURSTS COULD PRODUCE DAMAGING WIND GUSTS. WEAK ENVIRONMENTAL WINDS WILL RESULT IN SLOW AND ERRATIC STORM MOTIONS WHICH COULD RESULT IN LOCALLY HEAVY RAINFALL. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY... OPPRESSIVE HEAT AND HUMIDITY WILL CONTINUE INTO THURSDAY AND ONE MORE DAY OF HEAT ADVISORIES IS ANTICIPATED ACROSS THE NORTHERN HALF OF THE FORECAST AREA. SEA BREEZE INDUCED CONVECTION SHOULD KICK IN EARLY ENOUGH IN FLORIDA TO PRECLUDE REACHING THE 110-DEGREE HEAT INDICES NEEDED TO PROMPT AN ADVISORY THERE. WHILE HEAT INDICES WILL EDGE DOWNWARD FOR FRIDAY AND THE WEEKEND...IT WILL REMAIN HOTTER THAN NORMAL. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP EACH DAY...PEAKING IN THE AFTERNOON AND EARLY EVENING HOURS OVER LAND AND THE OVERNIGHT AND MORNING HOURS OVER THE GULF. ALTHOUGH A FEW OF THE STRONGER STORMS COULD PRODUCE LOCALLY STRONG WINDS AND HEAVY RAINFALL...NO ORGANIZED SEVERE WEATHER IS ANTICIPATED. .SPOTTER INFORMATION STATEMENT...
